ABSOLUTE MAXIMUM RATINGS (T amb =25°C)DESCRIPTION
The SMBJ series are TRANSIL TM diodesdesigned specifically for protecting sensitive equipment against transient overvoltages.
Transil diodes provide high overvoltage protection by clamping action.Their instantaneous response to transient overvoltages makes them particularly suited to protect voltage sensitive devices such as MOS Technology and low voltage supplied IC’s.

Note :The curves of the figure 3are specified for a junction temperature of 25°C before surge.
The given results may be extrapolated for other junction temperaturesby using the following formula :?V BR = αT *[T amb -25]*V BR (25°C)
For intermediate voltages,extrapolate the given results.
